'The purpose of my'invention is-to provide a multicolor press whichprints orimpresses'suitable. figures or impressions on paper or otherfiat surfaced material as maybe required;

A' further purpose of my invention is that fluid of any color or'consistency 'may be used.

A further advantage of my invention isthat twelve or more colors maybeused in printing one impression, each impression having; twelveor-more single units in twelve=or more colors.

Referring specifically to the drawings'ixrwhich alfluidimpression.material setby the press consisting of aiconventional.press'framelnamain press mechanismi, a'fountain kettle3, and a cleaner kettle 4. Thshaft 5 extendsfrom' the press head 6 and is journaled in theupper'plate I. Sai'dfplate 1; rectangular in shape; carriesthe slide rails'8'by means. of carriage, bolts .9, which run through the slots l0, andthesquare por tion ll of the bolts 9', preventing the turning of thebolts and'they are secured by the wing nuts I2. The slide rails 8 extend'iromthe' front edge of'the upper plate to the rearof the press (Fig.2). A slide member I3 is constructed of three beams l4, the ends of.which conform with the mortised edges l'5' of the rails. Each beam' hasthe brackets 16. screwed to it. Said brackets are slightly narrower inthe width than the beams, thus affording spaciousroom for themsertion ofa plurality of material membersylQ. The Fig. 11 illustratesthe spacingof the members [9, there being twelve shown butany'number may beemployed. There are four banksjof members I9, the members inea'chbank'areso constructed to allow each tooverlap the other one (see Fig.8).

The upper plate I is slottedat 20 (see Fig.2) atifour' points to permitthe. insertion of spacer rods 2l'which'extend from 'the mainpresstable22 with pressure springs'2'3 extendingifromthe table 22 to the undersurfaceofthe' upper-plate I always tendingxto keep'the plate 1." in'upward positionl A handle-2.41s secured'to the lower plate I 1 at itsfront edgev to" facilitate pulling the'unit'in.

and'out (see Figs. 2 and-11)..

Figure 1- illustrates the kettle '3 comprising a bracket'25xwhichissecured to 'a"'wall"26 (Fig; 9). The" kettle 3 is actually av pressure"kettle being secured by bolts ZS-around thegperiphery'and" provided"with pressure "gauge 21 "and a'safety' A series-of small containers 29are" tained in 'the' fountain kettle -3'. A cover 3 l with a; small hole32' covers each individual retainer. Extending from each'retainerf is apipe 33 provided with 'a cock 34, each .pipe continuing-to one of thematerial units. Said' units. comprise a nipple 33' to which the'pipe 33isjournale'd, a

bore' 3.5 which houses a valve'member; 36 which ends in a pusher rod.31. The units 19' "are screwed into the moldzplate38 which is :securedto the lower plate: ['1 by the screws 39. The molds Ml may be. ofanyrequired designgillus trated are Squares, triangle and hexagonalforms and are centered around the unit l9. Spaced between these moldsare pusher pins 4| driven outwardly by the springs 42 bound in the boresin the plate I! and abutted by the plugs 43.

In operation, a lever 44 extending from the side wall of the press ispushed downwardly from position A to position B. During this pressurethe mechanism (not shown) inside the press housing is actuated, drivingthe press mechanism 2 downwardly to a position shown in Figs. 5 and 20,at which point it will be seen that the pusher rod 31 of the fluid valve36 has been retracted allowing escape of the fluid material into themold and onto the paper. The fluid material is forced out of thefountain 3 under pressure which has been stored up in the kettle 3.Approximately twenty-five pounds of pressure is employed. At thisoperation almost all of the air pressure is expended thus requiring morepressure for the further operation. To provide for this the air valve 45is secured to the side wall of the press convenient to the lever 44. Asthe said lever 44 is moved from position B to position C, the handlebears on the roller 46 forcing the arm 41 downwardly on the pin 48opening the valves, thus permitting air to flow through the valvesthrough a pressure cylinder, not shown, into the press mechanism whichdrives the unit 2 upwardly again. The remainder of the air goes throughthe pipe 49, up through the check valve 50 and into the pressure kettle3, thus replenishing the necessary pressure.

Upon using of the unit 2 (Fig. 21). the pins 4| will bear against thepaper P holding it down and preventing it from adhering to the surfaceof the molds. This results in a series of sharp impressions 51 being ofthe same shape as the molds.

The paper is stacked onto the table 22 of the press and centered againstthe fences 52, said fences 52 being set by the adjusting screws 53. (SeeFig. 7.)

Figures 13 to illustrate the check valve 50, the valve 54 being drivenfrom its seat 55 by the air, against the spring 56 and the spaces 51permitting air to travel through.

A provision is made for cleaning the pipes when the change of colorfluid is required. A cleaner kettle 4 of similar design as the fluidkettle 3 is provided. Said kettle 4 is secured to the wall 26 by thesimilar bracket 25 but is cleaned by pressurizing. However, the twelvepipes 58 also run from the kettle 4 and are connected to the pipes 33below the cocks 34, and are also provided with the cocks 59. Whencleaning is necessary the cocks 34 are closed and the cooks 59 areopened thus permitting a flow of cleaner fluid through the pipes andinto the material pipes Ill. The mechanism 2 has been previously pulledout on the slide rails 8 (Fig. 11), thus facilitating cleaning the moldsat the same time. A counter 60 (see Fig. 2) is secured to the side wallof the press from which a rod 6| extends to the shaft 5. Every time theshaft is lowered the counter registers another impression through theaction of the rod 6| against the counter lever 62.

Although the drawings and specification disclose the best 'means inwhich I have contemplated embodying my invention, I desire in no way tobe limited to the details of such disclosure, for in the further use ofmy invention, slight changes in form and proportions may be made withoutdeparting from the spirit of the inven- -to said frame, press mechanismadapted to reciprocate said plate toward and away from contact with asheet on said material support, said plate being provided with anaperture in communication with each of said depressions, a valve carriedby each of said apertures, each of said valves having an inlet endconnected to one of said conduits and an outlet end in communicationwith one of said depressions, a valve actuating member provided at theoutlet end of each of said valves adapted to be actuated by contact withsaid sheet material upon the downward movement of said plate to therebydischarge said liquid material upon said sheet material within theconfines of the walls of each of said depressions.
